ABSTRACT OF THE DISCLOSURE In the invention, the sewing machine carries out winding of the thread by operating separately a thread winding mecha- nism and a clutch mechanism. A speed detector provided to a mechanism is relative with rotation of an upper shaft. If the thread winding were carried out t while said mechanism is left as engaged with a power source of the sewing machine, the speed detector would detect the rotation of said relative mechanism to stop a machine motor instantaneously, so that the thread winding cannot be performed when said relative mechanism is not released from the power source, and the needle bar is not actuated at winding the thread for safety in operation.
